Why are Medicare and Medicaid shown separately instead of combined?

They come from two different CMS data sources with no shared claim identifier, so they can't be reconciled into one number without double-counting or guessing. Every table and chart on this page keeps them fully separate.

Why is there no private/commercial revenue figure?

Private and commercial payer data comes from Transparency in Coverage files, which only publish negotiated rates — not claims or utilization volume. Without a volume figure, no revenue number can be computed for any provider from that data.

What does "Rank" mean in the Competitive Analysis & Benchmarks tables?

For a given CPT/HCPCS code, it's this provider's position by claims volume among all providers billing that same code at that geography level (State, National, or Georgia for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Georgia only?

Medicaid is administered per-state with no single national fee schedule, so a state or national comparison the way Medicare has one isn't available. Georgia (this provider's own state) is the only grouping that's conceptually meaningful.

Why are the numbers rounded to the nearest 10?

To avoid implying more precision than the underlying data supports at a single-provider level. Ratios are kept precise since they're a relative comparison, not a volume or dollar figure.

How current is this data?

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

JOHN CHUNG is enumerated as an NPI since 2006-04-26 (~20 years ago) and has generated Total Medicare revenue of $2.5M over his lifetime; there is no Medicaid billing on file (Medicaid revenue: none), so his public-payer footprint is effectively single-payer Medicare. The longevity of the NPI plus the concentrated Medicare revenue indicates an established Medicare-focused practice rather than recent entry.

Revenue concentration is high: the precomputed top-3 Medicare codes 17311, 14041, and 17312 together account for 45.6% of this provider's Total Medicare revenue. Individually those codes contribute $460.4K (18.9%) for 17311, $408K (16.7%) for 14041, and $245.1K (10.0%) for 17312, showing that nearly half of Medicare dollars are driven by a very small set of procedures.

The code mix and descriptions point to a Mohs surgery–centric practice with substantial reconstructive work: multiple Mohs procedure codes (17311, 17312, 17313) appear at the top of the list alongside large-tissue-replacement/reconstruction codes such as 14041, 14301, 14040, and 14021. These entries indicate routine performance of multi-staged excisions with on-site or same-session complex flap and graft repairs, consistent with an operator focused on excision of skin cancer and immediate reconstruction.

Competitive standing on key procedures is exceptional: 14041 ranks #1 of 1009 providers nationally (100th percentile; extreme outlier) and 17311 ranks #5 of 2969 (100th percentile; extreme outlier), while 17312 ranks #35 of 2770 (99th percentile; extreme outlier). These rank/percentile positions mean the provider is a national-volume outlier for both Mohs and large-area reconstructive closures and would be considered a dominant high-volume performer for these specific CPTs.

Beyond the top three, a cluster of reconstructive/complex-repair codes also posts high absolute revenue and percentile standing—examples include 14301 ($173.2K, 7.1% of Medicare revenue; ranks #7 of 1015, 99th percentile, extreme outlier), 14040 ($166K, 6.8%), 14021 ($121.8K, 5.0%), and 13121 ($91.8K, 3.8%). This pattern reinforces that revenue is driven not only by Mohs margins but by downstream complex closure and reconstruction services rather than predominantly by routine office visits or lesion destruction.

A smaller set of non-dermatologic codes appear at modest levels of revenue, notably radiation-simulation and planning codes 77280 ($87.5K, 3.6%), 77290 ($35.1K, 1.4%), and 77300 ($10.1K, 0.4%), which are described as typical or unremarkable volumes in national percentiles. These entries are an atypical adjunct in the claim mix for a Mohs-Micrographic Surgery Physician but are financially secondary to the primary Mohs and reconstructive CPTs; they warrant review for practice structure or multispecialty billing relationships rather than being primary revenue drivers.

Payer-mix implications are straightforward: with Total Medicare revenue of $2.5M and Medicaid revenue listed as none, the provider operates with effectively no Medicaid exposure on public claims data. That concentration presents downside risk to any policy or payment changes at the Medicare level and limits Medicaid-based comparators for in-state competitive analysis.

Operationally, the mix of extreme-outlier Mohs volumes and high-value reconstructive codes suggests a practice model that emphasizes high-throughput Mohs excisions with immediate complex reconstructions, supported by a long-tenured NPI (2006-04-26, ~20 years). For network or contracting analysts, this profile signals a specialty procedural center with concentrated Medicare revenue and national-leading volumes on specific surgical CPTs rather than a general dermatology/primary-care outpatient practice.
